I got this servlet off of coreservlets.com i want to know how i can edit it so that it connects to my database to get catalogItem instead of using static html.

I have made this servlet below which connect to my database how is it possible to merge the two so a catalogItem is got from mysql tables?

<pre>
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;

// Connects to a database to retrieve music data

public class browser extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();


// Database connection code starts here

Connection conn = null;

// loading jdbc driver for mysql (help in mysql.jar file in classpath)
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
} catch(Exception e) {
System.out.println(e);
}

// connecting to database
try{
// connection string for demos database, username demos, password demo-pass
conn = DriverManager.getConnection
("jdbc:mysql:/mysql tables link goes here!!");
// System.out.println("Connection to database successful.");
}
catch(SQLException se) {
System.out.println(se);
}

// Create select statement and execute it
try{
// Get the category from the input form
String categoryString = request.getParameter("category");
// check if no category
if (categoryString == "") categoryString = "Action & Adventure";

// Build up the SQL statement from our data requirements
String selectSQL = "select title, director, rating, year_released, price, stock_count, image_name "+
"from video_recordings "+
"where category = '" + categoryString + "'";
Statement stmt = conn.createStatement();
ResultSet rs1 = stmt.executeQuery(selectSQL);

// output html headers
String title = "Films in the " + categoryString + " genre" ;
out.println(ServletUtilities.headWithTitle(title) +
"<BODY BGCOLOR=\"#a00e0e\">\n" +

out.println("" +

" Number in stock\n" +
" image name"
);

// Retrieve the results
while(rs1.next()){
// getInt or getString or getFloat etc to get the appropriate column data
// wrap output in html for web
out.println("" +

// (must remember to always do this)
stmt.close();
conn.close();
} catch(SQLException se) {

}
}


}

Thank you for any help at all i'm really stuck on this so any help please lol :cheesy:

1) use code tags
2) don't put Java code in JSPs, they're meant ONLY for displaying results
